Buker capacity is generally designed for 1214 hours of full load operation. Let us calculate with 12 hours of operation hours. Coal consumption in 12 hours = 392 X 12 /24 =196 MT. Volume of bunker = 196 X 1000/800 = 245 M3. Take 10% of extra margin on bunker as some of coal stucked on bunker wall surface cannot be used for Boiler.

First, we have to convert power into energy. Energy is a measure of power output over time (energy = power x time). So to calculate energy output in watthours we have to multiply our power rating by the number of hours our plant is running. For example, if we have a 1000MW plant, its maximum energy output in a day would be 24,000MWh (1000MW x ...
